Enum LayoutError 

pub enum LayoutError {
    Json(String),
    Io(Error),
    NoStorageLayout,
    UnknownField(String),
    UnknownType(String),
    Shape {
        path: String,
        what: &'static str,
        expected: &'static str,
    },
    BadKey(String, String),
    Syntax(String),
    DynamicKey(String),
}

Layout parsing and path resolution failures.

Variants

Json(String)

The layout JSON did not parse.

Io(Error)

The artifact file could not be read.

NoStorageLayout

Neither a bare layout nor an artifact with a storageLayout key.

UnknownField(String)

No such top-level variable or struct member.

UnknownType(String)

The layout references a type id it does not define.

Shape

The path continues past something that cannot be indexed that way.

Fields

path: String

Path resolved so far.

what: &'static str

What was found there.

expected: &'static str

What the next segment would have to be.

BadKey(String, String)

A mapping key or array index did not parse.

Syntax(String)

The path string is malformed.

DynamicKey(String)

string/bytes mapping keys are hashed differently and not handled yet.

Trait Implementations

impl Debug for LayoutError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LayoutError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for LayoutError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for LayoutError

fn from(source: Error) -> Self

Converts to this type from the input type.
